HENRY D. ROBINSON, OF CHESTER, INDIANA.

HAY -LADDER.

SPECIFICATION forming part of Letters Patent No. 311,531, dated February 3, 1885.

Application filed February .21, 1884. (No model.)

To ctZZ whom, it may concern:

Be it known that I, HENRY D. ROBINSON, a citizen of the United States, residing at Chester, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Hay-Ladders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to that class of hayladders used upon farm-wagons in the trans portation of hay and grain.

In the drawing, the figure represents a perspective view of my improvement ready to be placed upon a wagon in which the curved bearing-rave on one side is omitted.

a a a a are sills of a lattice-framing, which havetheir bearing on cross pieccsi i i i. The cross-pieces i i" are of a length equal to the distance between the standards of an ordinary farm-wagon, while t 43 extend out the full width of the hay-ladder. The front sills, a a, extend from the front cross-piece, 0, back to the cross piece i, leaving an opening between the ends of the sills a and a, to allow the front wheels ofthe wagon to swing under the ladder in turning.

a a are short sills connecting cross-pieces z and *5 near the center of the ladder laterally.

'm m are rails resting upon posts 01 d, which are secured to the sills.

s s are braces placed angularly between the rails m m and the sills a a, having a post, d, between them,the whole forming a truss-frame, constituting a section of the side of the hay ladder.

c is a standard secured to the center of a' shaft, 00, situated immediately over and parallel with the rear cross-piece, i. The shaft 00 is provided with journals inserted in the ends, which journals pass through holes in an angle-plate, 9, allowing the shaft 00 a rotary motion, by which the standard 0 can be raised or lowered, as desired.

0 0 are transverse rails extending across the rear and front ends of the hay-ladder, resting upon the rails m m, embracing the width of the ladder, upon the outer ends of which longitudinal side rails, A, slightly curved, as shown, are placed, constituting the outline dimensions of the top of the hay-ladder in connection with the transverse rails 0 0. The side rails, A, are supported centrally by posts h h, the lower ends of which restupon the ends of the cross-pieces z t.

p p are metallic plates secured at an angle to the sill a and post (1 at the rear lower portion of the framing, having an opening through the same to receive the journal of the shaft :10, and at the same time serving as a brace and stay between the sill and post.

a is a short sill placed between the crosspieces i and i", and far enough inward from the line of the sills a a to allow the wheel of the wagon room to pass under the load in turnmg.

a n are short lateral rails extending from the posts h h to the rails in, m, and sustain the side rails, A, in the central portion of their length.

I) is an upright frame, connected at the top by cross-framing, and secured at the bottom to a rotary shaft in the same manner as the standard 0, in relation to which it occupies the opposite or front end of the hay-ladder, and is arranged so as to be raised or lowered in the same manner as the standard 0. The vertical frame b and standard 0 serve to sustain the front and rear ends of the load in position, and at the same time receive and retain the ends of the binding-pole when placed over the top of the load to hold the same in place.

Having thus fully described my improvement, what I claim as my invention, and desire to secure by Letters Patent, is

The combination and arrangement of the sills a, a, a, a, a, a, and e, the cross-pieces t' i t" i, rails m m, posts (I d, braces s 3, standard c, shaft or, angle-platep, side rails, A, rails 0 0, posts it h, rails a a, and frame I), all sub stantially in the manner specified, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY I). ROBINSON.
